RESUMO O presente artigo é um relato sobre uma fêmea de D. novemcinctus que foi capturada de forma imprevista, durante um projeto de avaliação sanitária de animais silvestres sinantrópicos do município de Toledo/PR (autorização Sisbio/Ibama n. 55109-1). Durante a avaliação física, amostras de fezes foram coletadas após defecação espontânea e encaminhadas para análise. O material foi submetido aos métodos de flutuação simples em solução hipersaturada de cloreto de sódio e centrífugo-flutuação em sacarose. Na leitura das lâminas obtidas pelo método de centrífugo-flutuação em sacarose, foram observadas estruturas com comprimento de aproximadamente 10µm, forma bicônica e um tampão em cada extremidade, compatíveis com esporocistos de Monocystis sp. Protozoários do filo Apicomplexa, os Monocystis sp., são geralmente parasitas de anelídeos, como as minhocas. Esse organismo é comumente correlato a pseudoparasitismo em vários animais, porém não foram encontrados relatos de pseudoparasitismo desse agente em tatus-galinhas, logo essa é a primeira descrição de Monocystis sp. em espécime de D. novemcinctus.

This is the case of a specimen of Didelphis albiventris with signs of respiratory difficulty after a dog attack. Thoracic radiographic examination revealed pneumothorax, pulmonary contusion, and rib fracture, but no alteration compatible with diaphragmatic hernia was observed. Pneumothorax was reduced and the other alterations were treated. However, clinical manifestations persisted, and thus a contrast-gastrointestinal radiographic study was performed, showing abdominal organs in the thoracic cavity and loss of diaphragmatic line. The surgical approach was instituted, with access to the diaphragm through median laparotomy. Through the diaphragmatic rupture, present in the left antimere, there were herniated liver and gastric portions, intestinal segments, and omentum. After inspection and repositioning of the abdominal organs, the diaphragm raffia was performed with single sutures interrupted with 3-0 Nylon thread. The patient’s complete recovery occurred 14 days after the surgical procedure, with remission of clinical manifestations and normality of thoracic images in radiographic studies.

Sarcocystis falcatula é responsável por prover a doença parasitária sarcosporidiose. O gênero possui cerca de 130 espécies, sendo classificadas quanto a sua patogenicidade. Apresenta-se sob a forma de oocistos, bem como cisto tecidual nos hospedeiros intermediários acometidos, sendo alojados em órgãos diversos, podendo levar o hospedeiro intermediário a óbito súbito sem sinais clínicos prévios. O presente relato tem por objetivo descrever um caso de sarcosporidiose em papagaio-do-congo (Psittacus erithacus). Os fragmentos colhidos foram clivados histologicamente e corados pela coloração padrão H&EConclui-se que é necessária a disposição de mais materiais informativos considerando a popularização da adoção de pets exóticos, garantindo sanidade a estes.

Background: The South American coatis (Nasua nasua) are capable of adapting to different habitats, which allowed them to exchange between domestic and wild areas, increasing the occurrence of traumas. Procedures performed in this species demand anesthetic protocols that take comorbidities into account and cause minimal cardiorespiratory depression as well as rapid recovery. It is in such context that locoregional anesthesia has become an essential tool. Thus, we aim to report the use of two techniques of locoreginal block: brachial plexus block and lumbosacral epidural block, in a Nasua nasua submitted to osteosynthesis of the radius and caudectomy due to trauma.Case: A adult male coati weighing 2.3 kg was referred to the Veterinary Medical Teaching Hospital of the Universidade Federal do Paraná (UFPR) - Setor Palotina with a history of trauma. Physical examination showed crackling in the radius and ulnar region, and also abnormal angulation in the distal portion of the tail. After taking x-rays, fractures were confirmed in the distal radius and in the distal portion of the tail. The patient was referred for surgery. After 8 h of water and food withdrawal, the animal was premedicated with a combination of ketamine (10 mg/kg), midazolam (0.3 mg/kg) and methadone (0.2 mg/kg), intramuscularly (IM). Induction of anesthesia was performed with propofol titrated to effect (total dose 4 mg/kg) and anesthesia was maintained with isoflurane in spontaneous ventilation using a non-rebreathing circuit (Baraka). It was evaluated heart rate (HR), respiratory rate (RF), end-tidal CO2 (EtCO2), expired isoflurane fraction (FE´Iso), oxyhemoglobin saturation (SpO2), electrocardiography (ECG), systolic blood pressure (SBP) and core temperature (CT) using a multiparametric monitor. After the stabilization period, the animal was positioned in lateral recumbence. A subscapular brachial plexus block was performed with bupivacaine (0.2 mL/kg) using a peripheral nerve stimulator to ensure the correct perineural deposition of the local anesthetic. During anesthesia, rescue analgesia was administered when there was a 20% increase in HR, RR or SBP compared to baseline values. Thus, in this case, two rescues with fentanyl (2 µg/kg) were necessary. The animal remained stable and, at the end of the first procedure, he was placed in ventral recumbence, with the hindlimbs pulled cranially in order to locate the lumbosacral space. Epidural injection was performed with lidocaine (0.18 mL/kg). Rescue analgesia was not necessary during the caudectomy procedure. The procedure had a total duration of 3 h and extubation occurred 3 min after inhalation anesthesia withdrawal. At the end of the surgery, the animal was medicated with meloxicam (0.1 mg/kg) and methadone (0.2 mg/kg). Two h after the end of the surgery, the animal was able to feed again.Discussion: The literature is scarce regarding anesthetic techniques in the Nasua nasua species, especially in the context of locoregional anesthesia. In this report, the protocol used as pre-anesthetic medication was considered satisfactory. Brachial plexus block is a safe technique for desensitizing the forelimb for surgical procedures distal to the scapulohumeral joint. Despite some morphological differences in the spinal anatomy of coatis, there was no difficulty in identifying the epidural space or inserting the needle. The absence of complications, and the hemodynamic stability during the anesthesia period, combined with the satisfactory recovery of the patient points to the success of the techniques used in the present report.

Background: The loss of natural habitats associated with the development of humanity resulted in the need for longer trips and greater interaction with highways by some animal species. Vehicle collision with animals is one of the main factors of pressure over wild animal populations in Brazil; veterinary surgery can play an important role for the recovery of these patients. The lesions commonly seen in animals hit by vehicles may comprise skin lesions, central nervous system injuries, intrathoracic and intra-abdominal complications, among which renal lesions are included. The aim of this work is to report the use of a total nephrectomy technique in a crab-eating fox.Case: A female, adult, 5-kg crab-eating fox (Cerdocyon thous Linnaeus, 1766) was received for emergency care at the Veterinary Hospital of Universidade Federal do Paraná at Palotina. The patient had been struck by a vehicle at a local highway, was unconscious, and exhibited signs of blood loss such as hypothermia, hypotension, and pale mucous membranes. As the clinical evaluation was performed, the patient was stabilized with pain management, correction of hypovolemia and hypothermia, and oxygen therapy. Blood samples were taken in case of the need for preoperative tests. Subsequently, the animal was submitted to the diagnostic imaging section to investigate possible injuries. No chemical restraint was necessary for the procedures. Radiography examination revealed loss of intra-abdominal contrast, which was confirmed to be free fluid on ultrasound examination. Immediately after imaging examination, the animal was taken to the surgical room for exploratory laparotomy. The surgical incision, which was performed over the linea alba, extended from the xiphoid process to the pubis. During surgery, free fluid was confirmed to be diffuse bloody fluid, which was observed in the abdomen; there was absence of lesions in all organs except the right kidney, which revealed clots and lacerations to the capsule, cortex, and medulla, resulting in poor viability of the organ. The condition required removal of the organ, which was performed with the conventional technique described for domestic animals. During the nephrectomy surgical procedure, the patient exhibited severe hypotension with the need of compensatory measures such as intravenous administration of crystalloid and colloid solutions, and vasoactive drugs, which were maintained during the period of surgery. Postoperative care included administration of analgesics and anti-inflammatory drugs for three days, and antibiotics for seven days. Hematological and renal profiles as well as ultrasound examinations were used for monitoring of clinical evolution. The patient was kept in isolation to avoid behavioral stress during hospital stay.Discussion: In this case, the importance of ultrasound diagnosis and viability of the nephrectomy technique were established for the specimen, which was returned to its natural habitat eighteen days after the vehicle collision, after authorization from the local environmental agency. Immediate care of a wild animal that suffers trauma is an important factor to increase success rate for recovery of fauna threatened by vehicle collisions. Early diagnosis associated with the employment of surgical techniques commonly used for domestic animals allow wild-animal clinicians and surgeons to improve viability of threatened populations.
